LEAKAGE-GUARD FOR WATERMMOTORS.

SPECIFICATION forming part of Letters Patent No. 682,346, datedSeptember 10, 190i.

`qiplication filed March 2, 1901.

To @ZZ whom t nul/y concern:

Be it known that I, DAVID P. SIMS, a citizen of the United States,residing at Lincoln, in the county of Lancaster, State of Nebraska, haveinvented certain new and useful Improvements in Leakage-Guards forWater- Motors; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which yit appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in leakage-guards forwater-motors; and it consists in the provision of bowlshaped guardswhich are fastened to the opposite sides of the motorcasing with theirbowl portions eX- tending over the hub of the motor-wheel.

My invention is clearly illustrated in the accompanying drawings, which,with the letters of reference marked thereon,form part of thisapplication, and in which-V-` Figure 1 is a vertical central sectionalview through a motor, showing the water guard cups or plates held to thecasing of the motor, through which casing the shaft rotates; and Fig. 2is au enlarged detail View, in side elevation, of one of said guardplates or cups. Fig. 3 is an enlarged sectional View through thebearing.

Reference now being had to the details of the drawings by letter, Adesignates the casing of the motor, which is centrally apertured toreceive the shaft B, on which the motorwheel C is mounted. The hubVportion of this wheel, which is cylindrical in outline with roundingends, is secured to the shaft by means of the screw D or other suitablemeans, and mounted about said shaft and secured to the inner walls ofthe casing opposite each other are the guard-cups E, which arebowl-shaped and held by their flanged bottoms to the opposite verticalside walls of the motor-casing with their hollow bowl portionsprojecting over the rounded ends of said hubs, the free ends of saidguard-oups being adjacent to the spokes of the motorwheel ou opposite`sides thereof, the circumferences of the cups being concaved, wherebySerial No. 49,609. (No model.)

the water falling` upon the same will run down and away from the hub andbearings. The outer face of each cup is recessed to re ceive a suitablepacking-ring F. At the outer ends of the wheel are the buckets C', theends of which extend beyond the inner adjacent ends of the guard-cups E,whereby as the motor-wheel rotates the cups will serve to catch thewater and prevent its passing out through the apertures in the casing,through which the shaft turns.

Mounted on either side of the casing are bracket-arms G, in the upperends of which are mounted the screw-threaded adjustable plugs II, whichhave their inner ends hollowed out, as at K, and hardened, forming abearing for one of the hardened antifriction-balls L.4 Secured to saidbracket Gr is a cup or casing M, which surrounds the ends of one plug Hand the shaft B, with antifriction-ball interposed between same. Mountedupon the upper end of each bracket G is a self-lubricating box N, havingan outlet-passage passing through said cup or casing M and held adjacentto the ball beneath,whereby a lubricant may be contantly fed to thebearings.

From the foregoing it will be observed that any wear between theantifriction-ball and the hardened sockets held adjacent thereto may betaken up by screwing in the plugs II, which are mounted opposite eachother at the upper ends of said bracket-arms. By the provision of thecups mounted within the casing the water which is thrown by centrifugalforce about the interior of the casing is prevented from passing outthrough the shaftopening and in contact with the bearings at the ends ofthe shaft.

. Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

l. In combination with the casing of a water-motor, a shaft passingthrough apertures therein, a cylindrical round-ended hub on said shaft,double-flanged guard-cups fastened by their outer iiauges to the wallsof the casing, the bottoms of the interiors of said cups conforming tothe ends of said hub, their exteriors being concave and their inner endsbeing adjacent to the spokes of the motorwheel, as set forth.
